Managing the patient with psychiatric issues in dermatologic practice

Patients often communicate emotions through their bodies and physical symptoms; the skin commonly serves as a means of expression in the patient-doctor relationship. It is important for the dermatologist to be able to indentify psychological issues that manifest in the skin and the interplay between psychiatric and dermatologic conditions. Delusional parasitosis, dermatitis artefacta, trichotillomania, and somatoform disorders all represent dermatologic conditions with underlying emotional causes. Many chronic dermatoses, such as psoriasis, atopic dermatitis, and acne, modulate and are influenced by psychosocial factors. Special issues, including significant medication interactions and the treatment of the “difficult” patient, are reviewed.
